Bottom Line: Inky mail is a free email client that pulls together all your inboxes and gives you unique views of your messages. The Mac version of Inky works well for personal accounts, but doesn't have many advanced features for email power users.

Bottom Line: If you're looking to truly simplify your mobile email experience, Mailbox should be your new best bud. It's easy to learn and encourages you to process mail rather than letting it build up in your inbox. Serious email users and organizational enthusiasts will immediately see what it lacks, however.
